Description
The application of supercritical carbon dioxide hasbeen attracting more attention in the synthesis ofbiodegradable polymers. Highly pure products withoutresidues can be recovered after the polymerization insupercritical carbon dioxide. In this book, thesynthesis steps of polyester-based biodegradablepolymers and the production of nanofiber scoffoldsfrom these polymers are reported in details.For the synthesis of polyester-based biodegradablepolymers, three types of block fluorinatedpoly(L-lactide-co-e-caprolactone) are synthesized insupercritical carbon dioxide using reactivestabilizers including inner fluorinated segment andpolylactide or polycaprolactone side chains.Perfluoro polyethers can be used as blood substitutesto deliver oxygen to tissues so that these materialsare promising for biomedical applications. For the production of nanofiber scoffolds,electrospinning process is used to fabricatenanofiber scaffolds from synthesized biodegradablematerials. Material characterization is carried out by nuclearmagnetic resonance spectroscopy, differential scanning calorimetry, gel permeationchromatography,optical microscopy and scanningelectron microscopy. Burcu Saner received a BS degree in Chemistry at MiddleEast Technical University in 2005 and a MSdegree in Materials Science and Engineering at SabanciUniversity in 2007. Mrs. Saner still continues her PhD researchat Sabanci University. Dr. Yusuf Menceloglu is currently a professorat Sabanci University in Materials Science and Engineering.
